DM54LS451/DM74LS451 Dual 8:1 Multiplexer General Description Features/Benefits The Dual 8:1 Mux selects one of eight inputs, DO through + 24-pin SKINNYDIP saves space D7, specified by three binary select inputs, A,B, and C. The = Twice the density of 74LS151 true data is output on Y when strobed by S. Propagation = Low current PNP inputs reduce loading delays are the same for inputs, addresses and strobes and are specified for 50 pF loading. Outputs conform to the ‘standard 8 mA LS totem pole drive standard.
